WAGON-DUMP.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed February 25, 1907. Serial No. 359,313.

To all whom it may concern:

Be it known that I, SAMUEL GUTH, citizen of the United States, residingat Washington, in the county of Tazewell and State of Illinois, haveinvented certain new and useful Improvements in Wagon-Dumps; and I dohereby declare that the following is a full,

clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to portable wagon dumps.

It has for one of its objects the simplification of devices of thischaracter.

It has for another object to provide driving mechanism for the samehaving in connection therewith a brake device which acts automaticallyto sustain the wagon at any height'when the power mechanism is stopped.

A further object is to provide an automatic friction brake which w1llpermit the elevation of the wagon through the driving mechanism andsustain the wagon in the position to which it may be elevated at thetime the raising movement is interrupted.

A further object is to provide a dump with driving mechanism andelevating means for the wagon and combining therewith braking meanswhich automatically sustains the wagon at any position.

A still further object of the invention lies in providing drivingconnection between the elevator and the power mechanism which operatesthe dump, of such a nature as to make it unnecessary to station theelevator and its conveyer or drag with its driving shaft axiallycoincident with the power shaft of the dump.

A still further object is to provide a driving connection between thedump and the elevator which will admit of the latter being connected anddisconnected from the power means of the dum at will without making itnecessary to exact ly aline the shafts.

Another object is to provide adjusting means between the elevator andthe conveyer for permitting the vertical adjustment of the formerwithout changing the position of the conveyer relatively to the platformof the dump.

To the end that my invention may be understood I have providedtheaccompanying drawings in which Figure 1 is a top view of the dum inits entirety. Fig. 2 is an end elevation o' a portion thereof. Fig. 3 isa side elevation of a bearing for the power shaft of the dump. Fig. 4 isa perspective view of the elevator and its conveyer or drag. Fig. 5 is aside elevation of a art of the dump. Fig. 6 is a side view of a rictionbrake. Fig. 7 is a side view of the head of the elevator.

The letter A indicates the platform of the dump having the usualapproaches B. At each side of the platform and extending longitudinallythereof is a lever arm C fulcrumed upon uprights D. Beneath the shortend of the levers is a raisable plank E for the front wheels of thewagon to be dumped. Attached to the. rear ends of the said lever armsare chains F whose opposite ends are attached to and adapted to be woundupon drums G carried on a transverse shaft H. I have not illustrated thelevers and the plank E fully since it is clearly shown and described inmy Patent No. 760,862 issued May 24th, 1904. Said shaft H is suitablyournaled in the platform and extends beyond the same at one end andcarries a beveled gear wheel J. Adjacent to the said wheel is a frictiondrum K provided with a brake-band L as clearly shown in Fig. 6 one endbeing attached to a stationary pin M or to other equivalent means so asto be fixed at that end. At the opposite end of the band is fastened amember N to which is loosely attached a rod O the opposite end of thelatter being pivoted to a hand lever P by which the said band istightened and loosened and held by means of a suitable latch and notchedquadrant common to many different classes of machines.

Extending at right angles to the shaft H is a power shaft Q carrying aloose beveled pinion R. This latter shaft has its bearings inmembersSsecured to the side of the platform, one of them being shown indetail in Fig. 3. Extending parallel to the shaft Q is a shiftable rodT, also having bearings in the members S described, in the holes Tthereof. Attached to or formed with the shifting rod is a fork U whichstraddles and engages a sleeve V which is slidable upon the power shaftQ and rotatable therewith as for instance by means of a key way andfeather (not shown), said sleeve having a projection thereon as at W forengaging a notch X of the same form in the hub of the pinion R. Upon oneof the members S is pivoted a lever Y (Fig. 1) the other end of thelever having attached thereto a pull-rod 3 extending within reach of theoperator stationed behind the conveyer.

At 4 is the elevator on which the conveyer or drag 5 is pivotallysupported, the shaft of said elevator being indicated at 6 and connectedby a knucklejoint 7 of any approved form to the power shaft Q; theopposite end of said elevator shaft having a similar knuckle joint 8 forreceiving the shaft of the horse power. The elevator is mounted upon theends of beams 10 by means of supporting bearings, the opposite ends ofthe beams having support on wheels 11, Fig. 4, there being a derrick 12pivoted on the said beams, the elevator extending therethroug has shown,there being suitable pulley on the elevator and derrick, to be describedlater.

I employ means on the elevator for adjustably carrying one end of the'conveyer and this consists of a cast-arm 14 at each side of theelevator, but one of which is shown, having pivotal connection with theelevator at 15, the upper ends having the shaft 16 of the conveyerextending therethrough as shown in Fig. 2. At each side of the said arm14 is an extension 17'slotted at 18, said slots being arranged in thearc of a circle described from the pivot point 15. Suitable bolts at 19serve to clamp the arms 14 to the side of the elevator and the looseningthereof permits the tilting of the arms on their pivots at 15 described.011 the shaft 6 of the elevator is a sprocket wheel 20, while a similarwheel 21 is carried on the shaft 16 of the conveyer and a sprocket chain22 serves to impart power from the former to the latter to drive thedrag-chain within the conveyer.

It will be observed that when the elevator is raised or lowered on itspivot on the shaft 6, (see Fig. 2) the conveyer will be shifted in thedirection of its length; this occurring if the arms 14 are relativelyrigid with the said elevator through the bolts 19. This shiftingmovement particularly if the hopper 23 is secured thereto will be ofsuch an extent that the wagon and conveyer will not be in properrelative position and the result will be that grain will be spilledoutside the conveyer.

Upon the platform are slide-irons 24 in an angling position being soplaced with reference to the wheels of the wagon as they approach them,that said wagon is always positioned exactly in the same place. It isnecessary, therefore, to shift the conveyer so that it will properlyregister beneath the delivery end of the wagon by means of the arms 14.

Longitudinal adjustment of the conveyer may be had irrespective of theangle of inclination of the elevator at any time. Vhen the desiredposition of the conveyer is found, and that of the elevator as well, thebolts 19 are tightened and the entire apparatus is ready for work. Theconveyer is then vertically tiltable upon its shaft 16, as in usualpractice, without having changed its position relative to the platformor the positively located wagon thereon when again lowered to the normalposition. It is evident that the lower ends of the arms 14 instead ofbeing pivoted at 15 could be pivoted at the shaft 6 of the elevator andthe extensions 17 secured by bolts 19 as already described. This wouldallow adjustment of the elevator and would likewise permit longitudinaladjustment of the conveyer. There is little difference, however, betweenthese two methods since in any case it is necessary to, at times, adjustthe conveyer in the direction of its length for the purposeshereinbefore mentioned and it would not always be convenient, in somestructures, to place the arms 14 at the shaft 6 on account of lack ofworking space.

As I construct the mechanism it is evident that the sprocket chain 22will become tightened or loosened according to the direction ofadjustment of the elevator and conveyer relatively, and I provide meansby which the chain can be given its proper adjustment. This consists inproviding a pin at 25 on one of the arms 14 which h as a holetherethrough (not shown) through which passes a rod 26 flattened andslotted at one end as shown and secured by means of a bolt 0 27 to theside of the elevator, the opposite end of the said bar having a curvedhead 28 to bear against the chain. When the chain needs adjustment, thebolt 27 is loosened and the bar 26 moved in the direction of its lengthto permit the chain to slacken or to take up the looseness thereof asthe case may be, the said bolt being afterwards tightened. However, anyother means may be employed to accomplish this purpose.

On the free end of the conveyer I attach a vertically adjustable member29, said member having adjustment through slots 30 and bolts 31. This isprovided in order that that end of the conveyer may be raised andlowered to adapt it to various heights of wagons while the other end canbe adjusted vertically to a limited extent by the members 14 described.As a matter of fact other equivalent means for supporting the free endof the conveyer and other means for adjusting it may be used.

I provide a peculiar adjusting tackle at the head of the elevator whichis clearly shown in Figs. 4 and 7, in which 32 is a pulley carried by astrap 33 extending across the elevator head, there being affixed to thesaid strap 33 a projecting arm 34 carrying a pulley 35, the plane ofwhich is parallel to the length of the elevator while the plane of thepulley 32 is at right angles thereto. To the top of the derrick 12 ishung a pulley 36. A rope 37 having one end secured to the windlass 13,before described, extends towards the top of the elevator beneath thepulley 35, up over the pulley 36, down around the pulley 32 thence upand is secured atits end in suitable manner to the top of the derrick.It will be seen that this arrangement requires little power on the partof the operator to control the elevator no matter what its weight maybe.

In operation the power applied to the elevator shaft 6 is transferred tothe shaft Q through the knuckle 7. The latter shaft runs free when theclutch-sleeve V is out of engagement with the pinion R, and revolvessaid sleeve free of the pinion. If, however, the rod 3 is pushed toshift the fork W toward the said pinion R the sleeve will engage thelatter and motion will immediately be imparted to the shaft H thuswinding the chains F upon the drums G to tilt the levers C and raise thewagon. Preferably the band brake L is set by means of its lever P at apoint where there will be sufficient friction to sustain the weight ofthe wagon through the shaft H; yet this friction is not so great as tohave any appreciable effect upon the power used in driving the machine.

The direction of drive of the shaft H is indicated in Fig. 6 by means ofthe dart this direction being clockwise and tends to pull upon the leverP to keep the band free there' of, but the moment the power isdisconnected the tendency of the shaft H is to rotate in the oppositedirection from that indicated, and this tends to tighten the band uponthe drum since the end of the band M is fixed. The wagon is, therefore,sustained in position by mere friction. When desired to lower the wagonthe lever is released by means of its latch and the'wagon is droppedslow or fast as may be desired, this depending upon the amount offriction that is kept upon the drum. It will be thus seen that the brakeis automatic to the extent that it sustains the wagon at any height towhich it may be carried on disconnectin the power at the same timepermitting the ump to operate without interruption or being affected inany way. In the raising movement but one lever is necessary for thecomplete control and it is not necessary to make use of the band brakeexcept when the wagon is to be lowered. As distinguished from otherdevices of this class the brake is normally set or in engagement withthe power means so that at any time the power is thrown off the wagon issustained in the raised position. Other devices apply the brake afterthe wagon sustaining means have been disconnected. Such a methodrequires mechanism I am able to dispense with thereby greatlysimplifying my construction, providing a machine of small cost, and onevery simple of operation.

An advantage in my dump is that the platform A with its attachedmechanism can be transported free of the elevator and conveyer, thelatter two elements being portable as a unit by themselves as well. Insetting up the machine the two parts i. 6., the dump, and the combinedelevator and conveyer, are each taken to their destination, the platformbeing placed in position and the elevator brought up beside it and theshaft Q inserted into the socket of the knuckle 7 without adjustment ofany kind. The elevator and conveyer, being portable by themselves, canbe used also with any other dump. The platform is kept light in weightso that less Work is required in moving it from place to place.
